Hypotension (Definition)

Hypotension is defined as "low blood pressure". Blood pressure is measured as two numbers and expressed as systolic blood pressure (sbp) / diastolic blood pressure (dbp). The sbp is the pressure that is generated when the heart squeezes. Dbp occurs when the heart relaxes. 120/70 is considered normal in adults. Less than 100/60 (of either number) can ...Read more

How does cfs relate specifically to fibromyalgia?

How does cfs relate specifically to fibromyalgia?

They are overlapping: Although cfs and fibromyalgia have distinct criteria that needs to be fulfilled, they are often diagnosed together. Fatigue is a common feature with cfs and in fibromyalgia..

Although pain is certainly a feature of both, but with a positive tender point exam is confirmatory with fibro. ...Read more

I'm trying to understand the relationship of hypoglycemia and hypotension. How does hypoglycemia cause hypotension?

I'm trying to understand the relationship of hypoglycemia and hypotension. How does hypoglycemia cause hypotension?

Yes, is difficult to: understand relationships between issues which are not related, at least not in ANY simple way. Blood glucose & blood pressure are two very different physiological behaviors. While both are controlled from the mind/brain, there have never been any evidence of any simple linkage. Linkage would be both highly inappropriate & life threatening because of many different life issues involved in each. ...Read more

How does brain inflammation relate to depression?

How does brain inflammation relate to depression?

Some recent thinking: suggests that brain inflammation might be the hidden culprit behind a lot of brain problems, including depression. How this works is not clear, but the corollary to this is that SSRI's actually work to relieve depression by reducing inflammation in the brain, again, this is not clearly understood, if true. ...Read more

Separate postural/orthostatic hypotension and tachycardia diagnoses, how does this work?

Need details: It's possible to have both conditions seperately, but they could are more commonly related or part of the same condition. It's likely best to spend some time having a heart rhythm specialist, go over your testing and results, and explaining it to you. A good history and physical examination is also helpful. Good luck. ...Read more

How does presyncope relate to heart failure?

How does presyncope relate to heart failure?

Several causes: Presyncope which is the sensation that you might faint but actually do not lose consciousness. This sensation could be due to rapid changes in position like standing up. It may be due to low blood pressure due to diuretics or other meds. A change in heart rhythm (too slow or too fast) can also cause this feeling. Less commonly very poor pumping power can cause this sensation. ...Read more

How does cfs relate to other illnesses such as fibromyalgia, multiple chemical sensitivities, gulf war syndrome, neurally mediated hypotension, Lyme disease, and candida?

How does cfs relate to other illnesses such as fibromyalgia, multiple chemical sensitivities, gulf war syndrome, neurally mediated hypotension, Lyme disease, and candida?

Simply put...: The underlying theme describes a constellation of signs and symptoms that we have absolutely no clear, concise idea how it biologically works, how to effectively treat it, and how to address its neuro-psychiatric effects, unfortunately, it is this ambiguity that is being exploited by some quacks, to spread misinformation about each of the diagnoses mentioned (and it's not exhaustive). ...Read more

How long does it take to build blood volume for someone with hypovolemia (related to orthostatic hypotension)?

How long does it take to build blood volume for someone with hypovolemia (related to orthostatic hypotension)?

Really fast: In an otherwise normal person, it is instantaneous if using IV fluids, and it is really fast if using oral fluids. Of course, the question is why is this happening? The REASON why there is hypovolemia can make a big difference in what to do about it, and how successful the treatments are. ...Read more

What is autonomic hypotension? Cardio defined my hypotension as autonomic w/blood pooling & arrhythmias. Prognosis? What can be done? More info please

Hypotension : This is due to loss of autonomic control that help to constrict veins in legs to push blood back to the heart. Due to this phenomenon , blood pools in leg veins and causes fall in blood pressure when you stand up from lying or sitting position. The best thing is to wear tight stockings in your legs as well as take time when you stand up. If you are lying down, sit for few seconds, then stand up. ...Read more

How does the vagus nerve relate to heart disease?

How does the vagus nerve relate to heart disease?

Brake on the heart: The vagus nerve (cranial nerve 10) is the "brake" on the heart. When it is activated it slows down the heart. In heart disease, it can be either helpful or part of the problem, depending on the particular disease process at work. If it's over-active, it can force the heart to beat to slowly. If it isn't working, it can let the heart beat to fast. ...Read more

How does alzheimer's related to your nervous system?

Is cfs related to depression?

Is cfs related to depression?

80% of CFS patients: Meet criteria for major depression. Cfs (chronic fatigue syndrome) patients do not have epstein-barr virus or any other viruses for that matter that can be found to clearly cause chronic fatigue syndrome. Other medical problems that can cause fatigue have to be looked for. Fibromyalgia, irritable bowel syndrome and temporomandibular joint disease are associated disorders but not causes for cfs. ...Read more

How do you know if its postural orthostatic tachycardia syndrome or cardiac autonomic neuropathy? Male 22. Not diabetic. Thanks

How do you know if its postural orthostatic tachycardia syndrome or cardiac autonomic neuropathy? Male 22. Not diabetic. Thanks

Here's my take: Postural orthostatic techycardia syndrome is fairly common and has a variety of different causes if the pathologist gets to look at nerve. Since you're asking to distinguish two not-well-understood illnesses, neither of which has a specific treatment, and since autonomic neuropathy is usually a diabetic's problem, i'd go with the good clinical fit -- if it seems like pots, then that's working dx. ...Read more
